arXiv:1709.01435

Abstract

Centimeter-sized single crystals of Sr $_{1.5}$ La $_{0.5}$ RhO $_{4}$ were grown by the floating zone method at oxygen pressures of 20~bar. The quality of our single crystals was confirmed by X-ray Laue, powder and single crystal X-ray diffraction, neutron and X-ray absorbtion spectroscopy measurements. At $\sim$ 50% electron doping we observe RhO $_{3}$ octahedral rotations of $\sim$ 8.2 $^{\circ}$ within the octahedral basal plane which are incompatible with space group I4/mmm. Our single crystal was further characterized by susceptibility, electrical transport and, finally, specific heat measurements showing a temperature dependent Debye temperature.
